  • Communication interface for interfacing a data bus of a computer to a high speed bipolar communication system
    Patent number: 5010480
    Abstract: A Digital Service (DS) interface interfaces a Personal Computer (PC) to the DS directly at the PC's data bus. The DS interface has independent transmit and receive memories for transmitting and receiving the digital data at high speeds. FIFO memories buffer data between the PC's data bus and the DS interface prior to being converted to bipolar digital signals before transmission and after being received and converted to amplitude discrete digital signals from bipolar digital signals.
